Product Description
AMSOIL SEVERE GEARŽ
Synthetic Extreme Pressure
(EP) Lubricants are premium
grade gear oils specifically
engineered for maximum
performance in severe duty
applications. These
state-of-the-art AMSOIL
formulations feature an
exclusive blend of high
viscosity, shear stable
synthetic base oils and an
extra treatment of
high-performance additives.
AMSOIL SEVERE GEARŽ
Synthetic EP Lubricants
maintain their viscosity for
long-lasting protection
against metal-to-metal
contact. The proprietary
AMSOIL additives form an
iron-sulfide barrier coating
on gear surfaces, providing
the ultimate line of defence
against wear, pitting and
scoring. AMSOIL SEVERE GEARŽ
lubricants help prevent
“thermal runaway” — a
phenomenon caused by a
lubricant’s inability to
control friction and
increased heat under
high-stress conditions. By
controlling thermal runaway,
AMSOIL SEVERE GEARŽ
Synthetic EP Lubricants
inhibit rapid lubricant
degradation and component
damage. Equipment runs
better and lasts longer with
AMSOIL SEVERE GEARŽ
Synthetic EP Lubricants.
Performance
AMSOIL SEVERE GEARŽ provides
performance beyond that
possible with conventional
gear oil. These AMSOIL
custom products offer
superior gear and bearing
protection, better friction
and heat reduction,
increased efficiency and
extended service life.

Temperature Extremes
AMSOIL SEVERE GEARŽ EP
lubricants excel in hot and
cold temperature extremes.
By design, they resist
breakdown from high heat,
preventing acids and
carbon/varnish formation.
Their wax free construction
also improves cold flow
properties, improving fuel
economy and cold weather
shifting.
Applications
AMSOIL SEVERE GEARŽ
Synthetic EP Lubricants are
excellent for severe
applications, such as
towing, hauling, steep hill
driving, commercial use,
plowing, racing, off-road
use, rapid acceleration,
frequent stop-and-go
operation and high ambient
temperatures.
Higher horsepower, towing
and hauling capabilities of
modern vehicles make turbo
diesel pick-ups, SUVs, vans
and delivery/utility
vehicles especially prone to
severe service. Other severe
duty vehicles include light,
medium and heavy-duty
trucks, buses, heavy
equipment, 4X4s, tow trucks,
race cars, tractors, and
motorhomes.
For
product service life in
differentials, consult your
owner’s manual or the
Original Equipment
Manufacturer (OEM) to
establish the application,
NORMAL or SEVERE.

Heavy Duty Class
8 Line Haul |
Follow the OEM drain
interval (miles or
hours) for synthetic
oil up to 250,000
miles or 3 years,
whichever comes
first. Otherwise,
drain at twice the
OEM interval for
conventional oil. |

Heavy Duty
Off-Road Vocational |
Follow the OEM drain
interval (miles or
hours) for synthetic
oil up to 120,000
miles or 1 year,
whichever comes
first. Otherwise,
drain at twice the
OEM interval for
conventional oil. |
For
product service life in
non-differential
applications, consult
owner’s manual or the OEM
for either normal or severe
synthetic oil service
intervals. Where service
intervals are unavailable,
drain at twice the interval
for conventional oil.
Gear oils
should be changed more
frequently when operating
vehicles or equipment in
dusty or dirty conditions
unless the gear system is
properly sealed and equipped
with membrane type
breathers.
Note:
AMSOIL does not support
extended drain intervals
where water contamination
occurs. Check and service
the gear oil frequently when
water contamination is
possible.
Recommended for use in
differentials, manual
transmissions and other gear
applications requiring any
of the following
specifications: API GL-5,
MT-1, MIL-PRF-2105E, Dana
SHAES 234 (Formerly Eaton
PS-037), Mack GO-J, or the
differential (hypoid) gear
oil specifications from all
domestic and foreign
manufacturers such as GM,
Ford and Daimler Chrysler.
Can also be used in axles
where an API GL-4 lubricant
is recommended.
AMSOIL SEVERE GEARŽ
(75W-110) provides
superior performance and
replaces competitors’
75W-110, 75W- 90 and 80W-90
gear oils. It delivers
better viscosity protection
than
SEVERE
GEAR 75W-90 and
better fuel efficiency than
SEVERE
GEAR 75W-140.
AMSOIL
SEVERE GEARŽ is compatible
with conventional and
synthetic gear oils. Mixing
AMSOIL gear oils with other
oils, however, will shorten
the oil life expectancy and
reduce the performance
benefits. AMSOIL does not
support extended drain
intervals where oils have
been mixed. Aftermarket oil
additives, other than those
specified by AMSOIL, are not
recommended for use with
AMSOIL gear oils.
AMSOIL SEVERE GEARŽ is
compatible with most limited
slip differentials. If
limited slip differential
chatter occurs, add
AMSOIL Slip-Lock™
Friction Modifier Additive.
